Frequently asked questions
Are my images uploaded to compress them?
No. Compression runs in your browser using the canvas API, so your images never leave your device.
Which format compresses best?
WebP usually produces smaller files than JPG at the same visual quality, though JPG has wider compatibility with older tools.
